STEPHEN R. PARKHURST, OF MONTGLAIR, NEW JERSEY, ASSIGNOR TO EMILY R. PARKHURST, OF SAME PLACE.

MACHINE FOR FEEDING, OPENING, AND MIXING WOOL.

SPECIFICATION forming part of Letters Patent No. 336,660, dated February 23, 1886.

Application filed July 31, 1885.

To all whom, it may concern.-

Be it known that I, STEPHEN R. PARK- HURsT, of Montclair, in the county of Essex and State of New Jersey, have invented an Improvement in Machines for Feeding, Opening and Mixing Wool, of which the following is a specification.

1n Letters Patent No. 323,523, granted to me August 4, 1885, a machine is shown for accomplishing the same object as my present invention. I have, however, improved upon the same in the particulars hereinafter set forth, in order to adapt the improvements to the accomplisliment of the additional objects, as stated.

In the drawings, Figure 1 is a vertical longitudinal section of my improved machine, and Fig. 2 is a diagram representing the belts and devices for giving motion to the parts.

The hopper for the wool is made of a partial cylinder, A, with heads A and pivots or trunnions A and there is a slot or opening at the under side, and the hopper is oscillated or partially rotated by a shaft, 1), with a crank or eccentric, and a connecting-rod, Z, to the end A of the hopper, as in my said patent, and there is a toothed cylinder, B,with a stripper, 0, to remove the burrs from the wool; but instead of a comb at one side of the slot in the hopper and a stationary bar, as in said patent, I make use of a swinging comb or lifter, c, projecting from one side of the cylinder or roller 0, and to this roller c'a partial rotation is given, first one way and then the other; and I prefer to use a rack, 6, on the hopperA, and a pinion, 7, on the shaft of the roller 0, to give the said motion to the comb or lifter c. This lifter 0 may have teeth in its edge, or it may be plain; and it is to be understood that the locks of wool pass down through the opening in the hopper and are caught by the teeth of the revolving cylinder B, and there is a table, 9, that partially covers the cylinder B, to lessen the space in which the wool can come into contact with the teeth of the cylinder B; and I use a toothed roller, 0 below the roller 0, the object of which is to detain the locks of wool until they are drawn down by the teeth of the cylinder B. This is accomplished by the roller 0 revolving at a slower speed than Serial No. 173,130. (No model.)

the cylinder B, and no locks of wool can be carried down by the cylinder B until sufir ciently spread and opened to pass between the cylinder B and the toothed roller 0 As the hopper A is reciprocated, the wool therein is shaken to the bottom and passes out upon the constantly loosened by the movement of the hopper. Only aportion of the wool can be carried down between the roller 0 and the cylinder B, and the comb 0 acts to lift the wool,

the fibers are opened out and drawn apart be tween the cylinder B and the hopper; and as the comb descends the fibers that have been opened are taken off by such cylinder B. The cylinder D opens the wool and spreads the same, and takes it off the cylinder B, and the surface-speed of D is to be about four times as much as that of the toothed cylinder B. I take the wool off the cylinder D by a brush blower, E, which revolves above a concave of wire at E, the object being to blow the dust and loose foreign substances downwardly and through the said grate and loosen the locks of wool, so that when received by the cylinder G they will be in a condition for carding. This cylinder G receives the locks of wool from the brush E", and it acts as a This cylinder H may be the ordinary cardtooth drum of a carding-machine; but I prefer to use a cylinder of steel teeth, as shown, and to place a stripper, M, above the same, so as to more thoroughly remove any foreign substances from the wool, and from this cylinder H the wool is taken by a brush-blower, I, there being a grating, I, over which the wool is blown, to allow dust and foreign substances to fall from the wool. The surface-speed of the cylinder G should be slightly greater than (that of the cylinder D, and the surface-speed of the cylinder H is preferably about double that of the cylinder G.

In the diagram, Fig. 2, I have illustrated the manner in which the respective shafts may be connected. The shaft of the cylinder I is represented as the driving-shaft, and from y the pulley 2 thereon motion is communicated to the shafts of the cylinders E G, and H, by

and by thus raising and detaining the locks feeder to convey the wool to the cylinder H.-

cylinder 13 and against the roller 0, and it is means of the belts 3, 4, and 5, to pulleys 10, 11, and 12 on said shafts, respectively.

13 is a pulley on the shaft of the cylinder G, and it gives motion to the shaft of the cylinder D by the belt 14 and pulley 15.

16 is a pulley on the shaft of the cylinder D, and from this pulley 16 motion is communicated to the shafts of the stripper O, roller 0 and stripper M, by means of the belts 17, 18, and 19 and pulleys 20, 21, and 22.

23 is apulley also on the shaft of the cylinder D, and this gives motion to the shaft of the cylinder B by the belt 24 and pulley 25.

I claim as my invention- 1. In combinatiom with thetoothed cylinder B, the hopper formed as a partial cylinder upon trunnions, the roller 0, comb a, and means, substantially as specified, for oscillating the hopper and roller, as set forth.

2. The combinatiomwith the hopper formed as a partial cylinder with an opening in the bottom, of the roller 0, comb c", toothed roller 0 toothed cylinder B, stripper O, and cylinder D, and means, substantially as described, for operating the moving parts, as specified.

3. The combinatiomwith the hopper formed as apartial cylinder with an opening in the bottom, and supported and oscillated substantially as set forth, of the roller 0, comb 0, toothed cylinders B and ,D, brush-blower E grate E below the brush, and the toothed cylinder G, to receive the Wool from the brush E, and means substantially as described, for operating the moving parts, as specified.

Signed by me this 24th'day of July, A. D. 1885.
